Filter videos by audio stream language

[taconaut]

Uses and exposes the audio language filtering being added with this PR: jellyfin/jellyfin#624

It currently looks like this:

Does the key/value have to be added to every file?

It does for now, that was inherited from Emby. We would love to implement a decent i18n library, do you have any experience with that? Translations would definitely be easier with something like Weblate.

[taconaut]

@dkanada unfortunately not, I'm a mainlya backend guy. It would be handy to have a fallback onto a default language, probably en-US.

[taconaut]

It would be nice to also localize the language code.
Does the backend have any localization so it could return a tuple containing the language code along with the localized language name? Or is everything done in the frontend? (I'm dicovering the project ;)

Looks good to me assuming merge conflicts in jellyfin/jellyfin#624 are fixed up.

We have some very basic localization in the frontend, no clue about the backend. There must be some code somewhere to get the language name because I have seen it in a couple of locations in the server dashboard. One location is Dashboard -> Library -> Metadata if you want to do some digging. It would definitely be better to show the language name instead of the language code here.

I'm a bit confused. The PR was merged but I can't find the language option on my Jellyfin 10.6.4.

[dkanada]

We had to revert this because the backend portion was never finished.
